Nurse Tank And Applicator Plumbing Alert

Tank Valve Excess Flow Check Warning

Frequently Asked Questions
when plumbing Anhydrous Ammonia tool bars

Question: What does the flow rating mean on tank valves? i.e. 95 GPM, 60 GPM and 45 GPM.
Answer: The withdrawal rate at which the excess flow check "pops". This has no bearing on how well the valve will perform during the application, only when it checks usually due to an accident where the hose breaks away from the tool bar.

Question: What is the difference 1-3/4" and 2-1/4" acme fittings?
Answer: 2-1/4" acme fittings allow more flow through the acme fitting resulting in higher application rates and speeds. Especially in colder weather.

Question: I have 2 heat exchangers plumbed with one hose, why did I not get much of an increase in my application rate when I added the second heat exchanger?
Answer: Heat exchangers rely on supply. Adding a second heat exchanger to the same supply line will not increase the application rate. You must increase the supply to increase the application rate by either adding a second supply line from another tank or upgrading to 1-1/2" hoses, fittings, valves and heat exchangers.

Question: I upgraded to 1-1/2" hoses but I'm still not getting what I was hoping for.
Answer: As with all supply lines the key is to maintain the supply line size. It is absolutely critical to use all 1-1/2" fittings in your supply lines and heat exchangers. Use full port fittings, valves and 2-1/4" acme adaptors. If you have swivel fittings or ball valves make sure they are all FULL PORT. Most common ball valves and swivels are not full port, make sure the unions, swivels, fittings and valves are 1-1/2" all the way through.

Question: All I have is 1000 gallon nurse tanks and I want to increase my application rates, what can I do?
Answer: Upgrade the nurse tank valves to the A-1406-G valves and change the acme fittings to 2-1/4" and upgrade your plumbing to 1-1/2". Even if you can't upgrade your plumbing or acme fittings you will still increase your applications rates by upgrading the nurse tank valves. Then you can progress to upgrading the rest of the plumbing when you can.

Question: I have 1000 gallon and 1450 gallon and 2000 gallon tanks, what size are my dip tubes?
Answer: Most if not all of the 1000 gallon tanks that are older then 15 years have 1-5/8" dip tubes. Some older tanks could be 1-1/2". The 1450 and larger capacity tanks are going to be 2-1/2" dip tubs.
